Mouse GPS Receivers

"...but the SiRF-based GPS's are better. tiny and damn fast fix...cold start typically takes less time than it takes me to hook up and start up the car. and hot start <5-10sec for 3D fix. i even get a fix inside garages sometimes. try that w/ your etrex. however not all SiRF-based GPS's are the same. I've heard bad things about the pharos unit and navman stuff is pretty bad too. if u get a serial GPS make sure it has battery backup of almanac & ephemeris data or it'll take a long time to cold start." - posted By Lincomatic on NS Forum   

"the leadtek is a little wider and flatter.
btw, both of them have magnets so you can stick them to your roof.
one thing i really like about the SiRF GPS's is there is a little utility that lets you tune everything from baud rate to what NMEA sentences it spits out to even the interval of each sentence." - posted By Lincomatic on NS Forum

Axiom CF GPS Receiver

"...Just purchased one from CompUSA. The CF gps is made by an Korean company called axiom GPS. (www.axiomGPS.co.kr).
It's based on SiRF star chipset (I believe it's SiRF I  chipset instead of SiRF II).
Initial test with Destinator 1.7.2 in sirf mode with baud rate of 38400, works great
The starcaddy software actually let you switch between NMEA and SiRF, so you don't need other tools to do this.
Acquisition time is great, reception is great even without external antenna in the car. Overall I'm very happy with this little device...

...BTW, if this CF GPS does indeed support WAAS, it's probably the cheapest CF GPS that can do that on the market. Compusa has this CF GPS with golf software for $179!"

Size Comparisons:

Edit - size comparison
Leadtek - 81.50x42.80x11.20x=39.1cc
Billionton - 87.87x42.80x10.40=39.1cc
Same volume, billionton is a tad longer and a tad thinner. So it seems the Leadtek would stick out quite a bit too, that's probably why Leadtek don't show a picture of the GPS in a PPC slot...
For reference the Pharos is:
80.00x57.00x22.00=100cc so it's quite a bit bigger !
